CVE-2024-41353 identifies a Cross Site Scripting (XSS) vulnerability in phpipam version 1.6, a popular open-source IP address management application. The vulnerability exists in the file app\admin\groups\edit-group.php, where insufficient input sanitization allows malicious input to be injected and executed within the context of the web application. This flaw is classified under CWE-79, which covers improper neutralization of input leading to XSS attacks. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L) indicates that the attack can be launched remotely over the network without any privileges but requires user interaction, such as clicking a crafted link or submitting malicious input. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component, potentially impacting the entire application session or other users. The impact on confidentiality, integrity, and availability is low to moderate individually but combined can lead to significant compromise, including session hijacking, unauthorized data access, or denial of service. No patches or exploits are currently documented, but the vulnerability's presence in a critical network management tool raises concerns for organizations relying on phpipam for IP address tracking and network infrastructure management.

The vulnerability poses a significant risk to organizations using phpipam 1.6, especially those managing large or sensitive network infrastructures. Successful exploitation can lead to the execution of arbitrary JavaScript in the context of authenticated users, enabling attackers to steal session tokens, manipulate user data, or perform actions on behalf of legitimate users. This can result in unauthorized access to network management data, disruption of IP address allocation processes, and potential lateral movement within the network. The impact extends to confidentiality breaches, integrity violations through data tampering, and availability issues if attackers cause application instability or denial of service. Given phpipam’s role in network administration, such compromises could cascade into broader network security incidents, affecting operational continuity and compliance with regulatory requirements.

To mitigate CVE-2024-41353, organizations should implement the following specific measures: 1) Apply input validation and output encoding in the edit-group.php component to neutralize malicious scripts, ensuring all user-supplied data is properly sanitized before rendering. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the phpipam web interface. 3) Limit user privileges and enforce the principle of least privilege to reduce the impact of potential XSS exploitation. 4) Monitor web application logs for suspicious input patterns or repeated attempts to exploit the edit-group.php endpoint. 5) Educate users about the risks of interacting with untrusted links or inputs within the phpipam environment. 6) Regularly update phpipam to the latest versions once patches addressing this vulnerability are released. 7) Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS attack vectors specific to phpipam’s URL patterns. These targeted actions go beyond generic advice and address the vulnerability’s root cause and exploitation vectors directly.
